Specification of Letters Patent.

Tatented April 9, 1907.

Application filed June 18,1906. Serial No. 322.216.

To all whom it may concern,.-

Be it known that I, ULYssEs A. Gaiman, a citizen of the United States,residing at Anaconda, in the county of Deerlodge and State of Montana,have invented certain new and useful Improvements in TwyerConstructions, of which the following is a lull, clear, and exactdescription, reference being had to the accompanying drawings, forming apart hereof.

My invention has relation to twyer constructions for converters, blast,cupola, and other furnaces; and it consists in the novel details ofconstruction more fully set lorth in the specification and pointed outin the claim.

In the drawings, Figure 1 is a -front elevation of my invention, showinga section of a converter-wall to which it is applied. Fig. 2 is atransverse vertical section on line 2 2 of Fig. 1. Fig. 3 is ahorizontal section on the plane of division between the [langes of the`wind-bev and twyers, respectively, on the line 8 3 of Fig. 2 lookingup. similar section looking down. cross-section on line 5 5 of Fig. 2.Fig. 6 is a vertical middle section of the valve-seat on line 6 6 ofFig. 7. Fig. 7 is a face elevation of the valve-seat. Fig. S is anenlarged vertical longitudinal middle section oi the valvecasing, andFig. 9 is a transverse vertical sec tion on line 9 9 of Fig. S.

The present invention while specially adapted for converters may withslight changes or modifications obvious to the skilled mechanic becomeavailable for lurnaces generally where a wind-box and twyers areemployed.

It has for its object to provide special securing means for connectingthe twyers to the Wind-box and facilitating the removal of them whenoccasion therefor arises, thereby permitting the twyers to be uncoupledfrom the furnace.

The invention embodies certain details and features of constructionwhose advantages willsbe more readily apparent from a detaileddescription of the invention, which is as 'follows:

Referring to the drawings, C represents a section of a wall of aconverter of any approved or prevailing design, to the outside of whichand at a convenient point vis secured the cylindrical wind-box B, whoselength will Fig. 4 is a Fig. 5 1s a depend on the`dimensions of theconverter. The pipe and hose connections which supply the wind-box withair are not here shown, as they form no part of the present inventionand may be of any suitable construction.

Formed along the peripheral wall of the wind-box is atangentially-disposed llange l, which is bolted to an angle-bar 2,carried by the converter-wall, the wind-box being provided near itsopposite ends with lugs 3, disposed parallel to the llange 1, which lugsare bolted to angle-brackets 4, carried by the wall of the converter.Disposed along a line diamctrically opposite to the linel where thellange 1 merges tangentially with the wall ol the wind-box are a seriesof hollow necks or bosses 5terniinating in oblong Ilanges 6, disposedtransversely to the axis of the cylinder B and terminating incentrally#disposed recesses 7, the portions of the llanges projectingbeyond the neck being reinforced by pairs ol ribs 8 8, located onopposite sides of each recess 7. Each twyer comprises a body portion 9,a nozzle 10, and allange 11, coupled to the body portion by a hollowneck 12. The llange 11 is provided with terminal recesses 7 which alinewith the recesses 7 of the [lange of the wind-box, the twyer beingsecured in position by the hinge-bolts 13, swung 'from pins between eachpair of ribs S 8 and passed through the alining recesses 7 7 andterminating in nuts 14;, bearing against the twyervflanges 11. Insertedinto the nozzle 10 is a pipe 15, which enters the lining of theconverter the necessary distance. The nozzle 10 passes through a .hollowring or boss 160i a plate 17, the boss having lormed therein anoutwardly-tapering passage lor the reception ol a band of asbestospacking 1S, this arrangement insuring a tight joint between the partsand the conical form of the opening preventing the packing-ring fromworking out alter it is once in place.

Formed in the outer wall ol the twyei opposite the nozzle 1.0 is anopening through which is inserted a valve-casing 19, provided' with arear opening 20 'for the l'ree passage therethrough ola poke-bar I), thecasing being further provided with the inclined ribs or ways 21 vfor therolling oll a ball-valve 22, the ball rolling up on the ways whendisplaced from its lowest position or seat upon the 1nsertion of thepoke-bar. The valve-seat IOO IOR

comprises a tube A23, having an inner end (lis-A posed obliquely to theaxis of the tube so as to afford aniore positive support fer the valveor ball 227 said tube 23 being inserted into the neck of the casing. The casing is provided with an outer flange 24, which is overlapped by acorresponding flange 25 of the valveseat, the whole being finallysecured to the wall 26 of the twyer by bolts 27 The fianges 24 25 andwall 26 are provided with alining openings for the insertion of thepolie-bar7 as fully shown in Fig. 2 of the drawings, the severalopenings in turn being all on a line of the rear opening 2O of thecasing and of the passage in the twyer-nozzle lO.

F roin the foregoing description it is apparent that all the advantagesenumerated for the construction here described are inherent therein-thatany twyer nia-y be reinoved from the wind-box for purposes of repair ata inoinents notice and as readily restored. The position of thevalve-casing and valve is `such as to corne outside of the currententering the nozzle from the wind-box, so that deterioration of theseparts from the heat of the charge is red uced to a ininirnuin.

Having described my invention, what I claiin isln combination with awind-box having a series of terininally-recessed flanges distributedalong its outer walls7 hollow necks connecting the flanges to the wallsof the WindboX, ribs disposed in pairs on opposite sides of the recessesand extending froin the flanges to the Wall of the wind-box, twyershaving correspondingly-recessed fianges adapted to engage the flanges ofthe wind-b 0X, and hingebolts suspended between each pair of ribs andpassed through the recesses or" the respective flanges, substantially asset forth.

In testimony whereof l affix niy signature in presence of two witnesses.
